router is BT Homehub V2B - I have no flash at the moment, so want to overlay from USB so we can have permanent storage & configuration.
I'm building a trunk from a few weeks back, kernel 3.1.4
I'm building for a ramdisk, as I have no flash.

all seems well, except i always end up with the device mounted as overlay-disabled, not as overlay.
Stick is formatted as a the raw device being ext4.

I have tried just setting target to /overlay.
I have tried installing luci and configuring through the web interface, then copying the config/fstab to the build directory, and confirmed it gets into the image.

fstab is currently:

config global automount
    option from_fstab 1
    option anon_mount 1
   
config global autoswap
    option from_fstab 1
    option anon_swap 0
   
config mount
    option device    /dev/sda
    option fstype    ext4
    option options    rw,sync,noatime
    option enabled    1
    option is_rootfs 1

config swap
    option device    /dev/sda2
    option enabled    0

One thing I notice is that the USB mount is almost the last thing in the dmesg.  Is this a problem, as it's obviously processing the fstab info as it is mounting it, just on the 'failed' location?

Is there something I need to put on the stick so it's recognised as a valid overlay sitck?
What is it that decides to mount to /overlay or /tmp/overlay-disabled?
Is it possible I'm missing the overlay-fs driver - Can't see any options to enable/disable it?

/etc/init.d/fstab overlay_enable

what does that modify?
'cos I'll need to get the config modifications into the ramdisk image that I flash

s

It fixes the md5sums

understood now.  so it modifies the stick itself, putting on the magic bit which makes it recognisable.
Will test as soon as I have a buildable image again; just broke everything .
thanks,
s

ok, tested now.  Seems nothing creates a .extroot.md5sum on my device.
overlay_enable just deletes this file (which never existed), and then asks for a reboot. 
So I assume this is meant to be created if not found on boot.

if i umount the stick, then call
/etc/init.d/fstab Start
I would hope this would attempt the mount, and it does, but still to overlay-disabled.
seems to call do_mount, which calls config_mount_by_section

From my interpretation, and my current config/ftsab (below), it looks like it needs option is_rootfs 1, but documentation says this should be unused.  (just tried with, and still no success )

Also, following things through, the md5checksum seems to be tested in preinit, but i'm sure usb is not up yet then?

s

config global automount
        option from_fstab 1
        option anon_mount 1

config global autoswap
        option from_fstab 1
        option anon_swap 0

config mount
        option target   /overlay
        option device   /dev/sda
        option fstype   ext4
        option options  rw,sync,noatime
        option enabled  1
        option enabled_fsck 0

config swap
        option device   /dev/sda2
        option enabled  0

latest - I think it's because the usb dwg-otg driver was a module, not in the kernel, and so usb was not available at preinit.  Just trying a complete rebuild with it in the kernel.....

still  no luck.

With dwg_otg driver in kernel, after preinit, something resets the device and kill it. 
USB device works fine if I break in at pre-init, but actual logon prompt is delayed as it tries to access the dead device.
